We report on the theoretical model and experimental results of the experiment made in a limit of absolute zero temperature (∼600  μK) studying the spin wave analog of black- and white-hole horizons using spin (magnonic) superfluidity in superfluid ^{3}He-B. As an experimental tool simulating the properties of the black- and white-hole horizons, we used the spin-precession waves propagating on the background of the spin supercurrents between two Bose-Einstein condensates of magnons in the form…

Formation Dynamics of Black- and White-Hole Horizons in an Analogue Gravity Model
• Physics
• 2020
We investigate the formation dynamics of sonic horizons in a Bose gas confined in a (quasi) one-dimensional trap. This system is one of the most promising realizations of the analogue gravity
Exceeding the Landau speed limit with topological Bogoliubov Fermi surfaces
• Physics

A common property of topological systems is the appearance of topologically protected zero-energy excitations. In a superconductor or superfluid such states set the critical velocity of
Probing Lorentz-Invariance-Violation Induced Nonthermal Unruh Effect in Quasi-Two-Dimensional Dipolar Condensates
• Physics, Education
• 2022
The Unruh eﬀect states an accelerated particle detector registers a thermal response when moving through the Minkowski vacuum, and this thermal phenomenon is believed to be inseparable from Lorentz
The latest frontier in analogue gravity: new roles for analogue experiments
So far, the philosophy literature has treated analogue experiments as if they have a single goal: to conﬁrm hypotheses about their target systems. But we should not be surprised if analogue

Hawking radiation, despite being known to theoretical physics for nearly 40 years, remains elusive and undetected. It also suffers, in its original context of gravitational black holes, from

It is demonstrated that the inner region has a "superluminal" dispersion relation, that is, that the group velocity of the surface waves increases with frequency, and some possible consequences with respect to the robustness of Hawking radiation are discussed.
Hawking radiation in sonic black holes.
The quantum treatment of the noninteracting case establishes a close relationship between sonic Hawking radiation and quantum tunneling through the barrier, and the possibility for experimental verification of this new transport phenomenon for ultracold atoms is discussed.

QUANTUM gravitational effects are usually ignored in calculations of the formation and evolution of black holes. The justification for this is that the radius of curvature of space-time outside the

The type-II Weyl and type-II Dirac fermions may emerge behind the event horizon of black holes. Correspondingly, the black hole can be simulated by creation of the region with overtilted Weyl or
